Question

Write two characteristics of a piece of sponge and a piece of rubber

Answer 1

Many things are made from rubber, like gloves, tires, plugs, and masks. ... Sometimes the word means only natural rubber (latex rubber). Natural rubber is made from the white sap of some trees such as the Hevea brasiliensis (Euphorbiaceae). Other elastomers, called synthetic rubbers, are made by chemical processes.
